    Default 150 facelift loosing power sometimes

    all started last sunday went over to my nans to pick them up for dinner got tback to mine and felt like there was no power thought nothing of it
    used it monday done a couple of miles then it lost power again
    feels like its in limp home mode wont revpast 3500

    it changes gear ok(auto) and runs ok with no mil light
    had a quick look over it to see if any sensors had come off as teh day before i ripped teh front bumper off when i went to far over a kurb and when i backed un the bottom of the bumper hit lol

    anyway thought well cant see anything wrong so went to go home and all teh power was there so carryed on did about 40odd mile all ok (town and motorway)

    going to work the other day i noticed it again on the way home ok
    yesterday the same this morning all ok
    but lost power on the same part of the road

    today i went for a good drive to get some bits and round town was ok but noticed as soon as i had been up a hill it seemed to be in limp mode
    but only a good size hill one where your powering up in for a while

    happened 3 times this afternoon all 3 times i had just gone up hill or over a bridge

    come back home and plugged it in only 2 codes come up
    1 p0070 ambient temp now the out side temp sensor wires had come off when i did the bumper but when i got the car the sensor had fallen off and teh wires ripped off so has new wires there and never been a problem

    2 p242f-75 did not know what it is

    now i pluged it in last night got them 2 codes and deleted them today both come back

    i have fixed teh out side temp


    any one know what it could be or areas to start looking

    i did take teh egr off the other week to give it a clean as it used to give a puff of smoke
    but that has stopped now
    and the egr was not that bad inside might take it off and give it a better soaking

    and teh only thing that comes up on the diagnostic is p242f code

    Think that is a dpf overload trouble code. Can be caused by sticking egr valves the actuator on it stucks to not just the valve
